Number of Girls = 3/5 × Number of boys
40 = Number of boys + Number of girls
40 = Number of boys + (3/5 × Number of boys)
40 = Number of boys × (1 + 3/5)
40 = Number of boys × 8/5
Number of boys = 40 × 5/8 = 25
Number of boys in the class is 25
40 = Number of boys + Number of girls
40 = Number of boys + (3/5 × Number of boys)
40 = Number of boys × (1 + 3/5)
40 = Number of boys × 8/5
Number of boys = 40 × 5/8 = 25
Number of boys in the class is 25
